I think a small improvement to the design would be to use words (COOK TIME / DEFROST GRAMS), with the "DEFROST GRAMS" text colored to match the defrost option on the bottom (which should also use the word, "DEFROST"). This would let you figure out what the dial does without having to think as much about it. You could also change the screen backlight color in DEFROST mode to reinforce the mode change.
